EVALUATION OF STATIC AND DYNAMIC PARASSITIC COMPONENTS ON THE INRIM 1 MN PRIMARY FORCE STANDARD MACHINE BY MEANS THE 500 KN SIX-COMPONENT DYNAMOMETER
Carlo Marinari
Abstract:
A recent improvement on the ancillary instrumentation and on the acquisition software of the 100 kN and 500 kN INRIM six-component dynamometers makes it possible to measure the parasitic components at static conditions and during the weight transition too, in order to weigh up the influence of the dynamic phenomena on the value of axial load.
This paper presents the main results of the evaluation of the parasitic components arising in static and dynamic conditions on the INRIM 1 MN force standard machine by using the INRIM 500 kN six-components dynamometer. It shows that the values of dynamic component can be several time bigger that the values calculated at static conditions, and that they must be measured and monitored in order to avoid any influence on the machine-dynamometer interaction and on the uncertainty of the main axial load.
